After graduating from Duke University in 2009, Will Harlan began working on a consumer-internet startup in San Francisco, while simultaneously and quietly laying the groundwork for a wine project. Announced in 2013, The Mascot—a wine made from the younger vines of the Harlan family domain—marked Will’s official shift into the wine business. In 2017, Will assumed leadership of Promontory, the Harlan family’s most recently formed winegrowing endeavor in the Napa Valley. Beginning in January of 2021, Will’s responsibilities expanded to encompass oversight of all the family’s winegrowing properties when his father appointed him Managing Director of Domain H. William Harlan, which comprises Harlan Estate, BOND, Promontory, and The Mascot.
